Description

A kind of medical crutch

Technical field

This utility model relates to a kind of medical crutch, divides and belongs to medical rehabilitation utensil technical field by International Patent Classification (IPC) (IPC).

Background technology

At medical rehabilitation utensil, for one of most important recovering aid instrument of shank and foot, and existing crutch is mostly the trigone that wedge angle arranges towards bottom surface, contact and realize with ground and electrically contact support and such crutch is sharp corner, and on ground when sliding or ice and snow weather, usually occur that support force is not enough and the problem such as cause not supporting, use like this people of crutch very easily to slide into, thereby increase the weight of the state of an illness.

Thus, the inventor considers existing crutch structure to improve, and this case produces thus.

Utility model content

For the deficiencies in the prior art, this utility model provides a kind of medical crutch, and it utilizes the strong point of bracing frame Zheng family crutch, thereby effectively avoids the phenomenon such as skid occurring because a single point supports, and also further guarantees the safety of user.

For achieving the above object, this utility model is achieved through the following technical solutions:

A kind of medical crutch, this crutch is the isoceles triangle supporting construction that wedge angle arranges towards bottom surface, the closed angle end of this crutch is enclosed with slipmat, thereby forms fulcrum type supporting construction; The all sides of described crutch are provided with bracing frame, and this bracing frame comprises that at least three support claws are uniformly distributed as axle center taking crutch closed angle end, thereby form the triangle multiway supporting construction of crutch; Each support claw comprises support chip and stator, described stator is fixed on crutch and its one end is provided with groove, and this groove inwall indentation, described support chip and stator coordination hinge, this support chip one end indentation and with stator on corresponding end sawtooth intermeshing, thereby form the support angle adjustment structure of support claw.

Further, the other end of described support chip is enclosed with slipmat, thereby forms Anti-slip type supporting construction.

Further, the object of described slipmat is the pad of the frictional force on increase and ground, and any pad that increases frictional force all can use.

Further, between described stator and support chip, be connected by an elastic component, thus the resetting structure of formation support claw.

Further, described crutch also comprises supporting leg, and this supporting leg is articulated with on crutch lateral wall and can rotates taking pin joint as axle center, thereby realizes folding and the stretching, extension of this supporting leg.

Further, described supporting leg comprises hinge bar and gripper shoe, and described hinge bar one end and gripper shoe are hinged and can rotate taking pin joint as axle center, realizes folding and the stretching, extension of gripper shoe with respect to hinge bar.

Further, described gripper shoe is telescopic plate body.

Further, described gripper shoe comprises at least two mutually inside and outside plate bodys of socket, and inner plate body is placed in the cavity of outer plate body, and in the cavity of plate body, carries out reciprocal stretching motion outside, thereby forms telescopic structure.

Further, described inner plate body one end is L-shaped, and the L-type projection that this end is corresponding with outer plate body inwall coordinates clamping, thereby forms the Telescopic positioning structure of gripper shoe.

Further, described crutch upper end is the pole suitable with human body axillary fossa, on this pole, is enclosed with foam-rubber cushion.

Compared with prior art, advantage of the present utility model:

1, this utility model increases bracing frame on the basis of existing technology, supports thereby realize multipoint mode, guarantees the safety in its use;

2, described bracing frame is made up of at least three support claws, and each support claw all has adjustment structure, thereby meets difference and require the demand of user, also increases the comfortableness in using simultaneously;

3, this utility model also increases supporting leg on crutch body, this supporting leg is to be used in fracture user to have a rest and use after long-time walking, can stretch out and can be folded in crutch one side simultaneously, this supporting leg comprises the effect that two parts realization regulates for different users, user is positioned in gripper shoe hindering lower limb, raises the rehabilitation such as rest requirement thereby reach injured lower limb.
